Description

Die Erfindung.bezieht sich auf ein Anzeigeinstrument mit einem Gehäuse, welches zur Vorderseite hin einen Flansch aufweist, gegen den mittels eines Frontringes eine durchsichtige Deckscheibe und/oder ein Ziffernblatt gehalten ist. Solche Anzeigeinstrumente sind zum Beispiel in Kraftfahrzeugen angeordnet und allgemein bekannt. Sie werden üblicherweise in einer Öffnung einer Einbauplatte mittels eines rückseitigen Bügels gehalten.The invention relates to a display instrument with a housing which has a flange towards the front, against which a transparent cover plate and / or a dial is held by means of a front ring. Such display instruments are arranged in motor vehicles, for example, and are generally known. They are usually held in an opening in a mounting plate by means of a rear bracket.

Bei den bekannten Anzeigeinstrumenten ist die Deckscheibe mittels eines Metallringes gegen den Flansch des Gehäuses dadurch gehalten, daß der Metallring durch Umbördeln diesen Flansch und die Deckscheibe U-förmig umgreift. Das Erzeugen der beiden erforderlichen Umbördelungen ist ein relativ zeitaufwendiger Arbeitsgang und bedingt eine hierzu speziell ausgebildete Maschine.In the known display instruments, the cover plate is held against the flange of the housing by means of a metal ring in that the metal ring surrounds this flange and the cover plate in a U-shape by flanging. The generation of the two required flanges is a relatively time-consuming operation and requires a machine specially designed for this purpose.

Der Erfindung liegt die Aufgabe zugrunde, ein Anzeigeinstrument der eingangs-genannten-Art zu entwickeln, welches durch eine rasche und einfache Montagemöglichkeit seiner Deckscheibe und/oder seines Ziffernblattes billig herstellbar ist.The invention has for its object to develop a display instrument of the type mentioned, which its quick and easy installation Cover plate and / or its dial is cheap to manufacture.

Diese Aufgabe wird Erfindungsgemäß dadurch gelöst, daß gegen die Rückseite des Flansches ein auf das Gehäuse von der Gehäuserückseite her aufgeschobener Klemmring anliegt, auf den der-Frontring mittels einer Schnappverbindung axial gehalten ist.This object is achieved according to the invention in that a clamping ring pushed onto the housing from the rear of the housing bears against the rear of the flange, on which the front ring is held axially by means of a snap connection.

Der Hauptvorteil der Erfindung liegt darin, daB die Deckscheibe und/oder das Ziffernblatt mittels der Schnappverbindung ohne jedes Werkzeug am Flansch des Gehäuses des Anzeigeinstrumentes befestigt werden können. Dadurch ist die Montage des Anzeigeinstrumentes rascher als bisher durchführbar und verlangt kein besonderes Geschick und keine hohe Sorgfalt. Wenn der Frontring in den Klemmring einschnappt, dann ist zwangsläufig sichergestellt, daß der Frontring die Deckscheibe und/oder das Ziffernblatt zuverlässig gegen den Flansch des Gehäuses hält.The main advantage of the invention is that the cover plate and / or the dial can be attached to the flange of the housing of the display instrument by means of the snap connection without any tools. As a result, the mounting of the display instrument can be carried out more quickly than before and requires no special skill and no great care. If the front ring snaps into the clamping ring, it is inevitably ensured that the front ring reliably holds the cover plate and / or the dial against the flange of the housing.

Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, daB der Klemmring auf seiner Außenmantelfläche mehrere Rastnasen, und der Frontring entsprechende über die Rastnasen greifende Rastvertiefungen hat. Diese Ausgestaltung ist fertigungstechnisch besonders dann günstig, wenn der Frontring und der Klemmring aus Kunststoff bestehen und im SpritzguBverfahren hergestellt werden. Die Rastvorsprünge und Rastnasen können so gestaltet sein, daß keine Probleme bei der Entnahme der Teile aus der SpritzguBform entstehen.An advantageous embodiment of the invention consists in that the clamping ring has a plurality of latching lugs on its outer lateral surface, and the front ring has corresponding latching depressions which extend over the latching lugs. This configuration is particularly favorable in terms of production technology if the front ring and the clamping ring are made of plastic and are produced by injection molding. The locking projections and locking lugs can be designed so that there are no problems with the removal of the parts from the injection mold.

Wenn aus der Außenmantelfläche des Klemmringes mehrere Zentriervorsprünge in entsprechende axiale Nuten der Innenmantelfläche des Frantringes ragen, dann wird auf einfache Weise erreicht, daß die Rastnasen zwangsläufig von den Rastvorsprüngen voll überdeckt werden, so daB eine sichere Verrastung eintritt.If several centering projections protrude from the outer lateral surface of the clamping ring into corresponding axial grooves of the inner lateral surface of the fringe ring, then it is easily achieved that the latching lugs are inevitably fully covered by the latching projections, so that a secure one Latching occurs.

Von Vorteil ist Es auch, wenn zwischen dem Frontring und der Deckscheibe eine axiale Toleranzen ausgleichende elastische Rundschnurdichtung vorgesehen ist. Diese elastische Rundschnurdichtung vermag neben ihrer Dichtfunktion auch die Funktion eines Längenausgleiches auszuüben, so daB die erfindungsgemäß gestalteten Bauteile mit relativ graben Toleranzen gefertigt werden können, ohne daB die Gefahr besteht, daB der Frontring nicht mehr auf den Klemmring zu verrasten vermag oder daß die Deckscheibe nicht hinreichend fest auf den Flansch des Gehäuses gepreBt wird.It is also advantageous if an elastic round cord seal which compensates for axial tolerances is provided between the front ring and the cover disk. In addition to its sealing function, this elastic round cord seal can also perform the function of length compensation, so that the components designed according to the invention can be manufactured with relatively narrow tolerances without the risk that the front ring can no longer lock onto the clamping ring or that the cover plate cannot is pressed sufficiently firmly onto the flange of the housing.

Die im Anspruch 5 angegebene Ausführungsform der Erfindung ist vor allem dann zweckmäßig, wenn für verschiedene Einsatzfälle identische Anzeigeinstrumente verschieden weit aus der Einbauplatte ragen sollen oder wenn für ansonsten identische Anzeigeinstrumente unterschiedlich dicke Deckscheiben zum Einsatz kommen. Der Frontring braucht bei dieser.Ausgestaltung in solchen Fällen nicht verändert zu werden. Man kann entweder den Klemmring auf die erforderliche Höhe abdrehen oder von vorneherein einen schmalen Klemmring vorsehen, gegen den fallweise Distanzringe geschoben werden, die gegen die Einbauplatte und der Anlagefläche des Klemmringes anliegen. Abgesehen von der Möglichkeit einer einfachen Anpassung an verschiedene räumliche Gegebenheiten ist bei dieser Ausführungsform auch sichergestellt, daß bei Befestigung der Anzeigeeinheit in der Einbauplatte keine Kräfte in die Schnappverbindung gelangen, wodurch die Rastnasen oder Rastvertiefungen beschädigt oder zerstört werden könnten.The embodiment of the invention specified in claim 5 is particularly expedient if, for different applications, identical display instruments are to protrude from the mounting plate to different extents, or if cover disks of different thicknesses are used for otherwise identical display instruments. The front ring does not need to be changed in such cases. You can either turn the clamping ring to the required height or provide a narrow clamping ring from the outset, against which spacer rings are pushed, which abut against the mounting plate and the contact surface of the clamping ring. Apart from the possibility of a simple adaptation to different spatial conditions, this embodiment also ensures that no forces get into the snap connection when the display unit is fastened in the mounting plate, as a result of which the detents or recesses could be damaged or destroyed.

Die Figur 1 zeigt den vorderen Teil eines Gehäuses 1 eines Anzeigeinstrumentes. Dieses Gehäuse weist auf seiner Vorderseite her einen Flansch 2.auf, auf den in der Zeichnung gesehen von oben her zunächst ein Ziffernblatt 3 und darauf eine Deckscheibe 4 aus beispielsweise Glas anliegt. Unterhalb des Flansches 2 befindet sich ein Klemmring 5.FIG. 1 shows the front part of a housing 1 of a display instrument. This housing has a flange 2 on its front side, on which, as seen in the drawing from above, a dial 3 and a cover plate 4 made of glass, for example, abut thereon. A clamping ring 5 is located below the flange 2.

Ein Frontring 6 umgreift die Deckscheibe 4, das Ziffernblatt 3 und den Flansch-2 sowie den Klemmring 5 und schließt dabei eine elastische Rundachnurdichtung 7 ein, die auf der Perpherie der Deckscheibe 4 aufliegt. Der Frontring 6 und der Klemmring 5 sind durch eine Schnappverbindung 8 zusammengehalten. Die Schnappverbindung 8 ist dadurch gebildet, daß am Klemmring 5 mehrere radial nach außen ragende sägezahnförmige Rastnasen 9 vorgesehen sind, deren flachere Flanke zum Flansch 2 hin verläuft. Im Frontring 6 sind den Rastnasen 9 entsprechende Rastvertiefungen 10 vorhanden.A front ring 6 encompasses the cover plate 4, the dial 3 and the flange 2 and the clamping ring 5 and thereby includes an elastic circular axis seal 7 which rests on the periphery of the cover plate 4. The front ring 6 and the clamping ring 5 are held together by a snap connection 8. The snap connection 8 is formed in that a plurality of radially outwardly projecting sawtooth-shaped locking lugs 9 are provided on the clamping ring 5, the flatter flank of which extends towards the flange 2. In the front ring 6, the locking lugs 9 corresponding locking recesses 1 0 are available.

Die Figur 1 läßt weiterhin erkennen, daB der Klemmring 5 über die Breite des Frontringes 6 in der Zeichnung gesehen nach unten reicht und mit einer Anlagefläche 11 gegen eine Einbauplatte 12 anliegt. Nicht dargestellt ist ein Spannbügel, durch den auf übliche Weise das Gehäuse 1 in der Zeichnung gesehen nach unten gezogen wird, so daß die Anlagefläche 11 fest gegen die Einbauplatte 12 gehalten ist und das Gehäuse 1 dadurch fest in der Einbauplatte 12 sitzt, ohne daß zusätzliche Kräfte in die Schnappverbindung 8 gelangen können.FIG. 1 also shows that the clamping ring 5 extends downward over the width of the front ring 6 in the drawing and bears with a contact surface 11 against a mounting plate 12. Not shown is a clamping bracket through which the housing 1 is pulled downward in the usual manner, so that the contact surface 11 is held firmly against the mounting plate 12 and the housing 1 is thereby firmly seated in the mounting plate 12 without additional Forces can get into the snap connection 8.

Die Figuren 2 und 3 zeigen, daß der Klemmring 5 insgesamt vier Rastnasen 9, 9a, 9b, 9c hat. Zusätzlich zu diesen Rastnasen 9 sind in der Außenmantelfläche des Klemmringes 5 zwei Zentriervorsprünge 13, 14 vorgeshen, deren Bedeutung später anhandader Figuren 5 und 6 erläutert wird.Figures 2 and 3 show that the clamping ring 5 has a total of four locking lugs 9, 9a, 9b, 9c. In addition to these locking lugs 9, two centering projections 13, 14 are provided in the outer lateral surface of the clamping ring 5, the meaning of which will be explained later with reference to FIGS. 5 and 6.

Figur 4 läBt erkennen, daB die Rastnasen nach oben hin flache Flanken 15 und nach unten hin im rechten Winekl zur Mantelfläche des Frontringes 6 verlaufende Flanken 16 haben. Durch diese Gestaltung ist der Frontring 6 nach dem Einschnappen der Schnappverbindung 8 nicht mehr vom Klemmring 5 zu lösen. Selbstverständlich ist es jedoch auch möglich, die Schnappverbindung 8 so auszubilden, daß durch Zug am Frontring 6 ein Entrasten stattfinden kann.FIG. 4 shows that the latching lugs have flat flanks 15 upwards and flanks 16 running downwards in the right winekl to the outer surface of the front ring 6. With this design, the front ring 6 can no longer be detached from the clamping ring 5 after the snap connection 8 has snapped in. Of course, however, it is also possible to design the snap connection 8 in such a way that unlatching can take place by pulling on the front ring 6.

Die Figur 5 zeigt im linken Bildteil eine der Rastvertiefungen 1o im Schnitt und im mittleren Bildteil einen Blick von auBen auf eine der drei anderen Rastvertiefungen. Die Figur 6 läBt zwei diametral in der unteren Innenmantelfläche des Frontringes 6 von unten her hineinführende Nuten 17, 1B erkennen, wobei die Nut 18 auch in Figur 5 dargestellt wurde. Diese Nuten 17, 18 sind so bemessen, daB sie die Zentriervorsprünge 13, 14 aufzunehmen vermögen.FIG. 5 shows one of the locking recesses 10 in section in the left part of the image and a view from the outside of one of the three other locking recesses in the middle part of the image. FIG. 6 shows two grooves 17, 1B leading diametrically into the lower inner lateral surface of the front ring 6, the groove 18 also being shown in FIG. These grooves 17, 18 are dimensioned such that they are able to receive the centering projections 13, 14.

Zum Aufschieben des Frontringes 16 auf den Klemmring 5 muB der Frontring sich in einer solchen Winkelstellung zum Klemmring 5 befinden, daB die Zentriervorsprünge 13, 14 in die Nuten 17, 18 gelangen können. In dieser Stellung vermögen die Rastnasen 9 exakt in die Rastvertiefungen 10 des Frontringes 6 zu schnappen.To push the front ring 16 onto the clamping ring 5, the front ring must be in such an angular position with respect to the clamping ring 5 that the centering projections 13, 14 can get into the grooves 17, 18. In this position, the locking lugs 9 can snap exactly into the locking recesses 1 0 of the front ring 6.
